"For an average 1,000 kilowatt-hour residential bill, the fuel refund will be $7.59 in September and $10.06 in October," Entergy Texas reported in a news release. "In addition to the refund, customers will also see a drop in the fixed fuel factor, which is a pass-through charge to recover costs for fuel used to make electricity. This charge will change from its current amount of $42.27 per the average 1000 kilowatt-hour residential bill to $36.20, or about $6 in savings."

A comparison to current bills shows that the average bill in August was $121.61, the company reported. That will drop by 11 percent to $107.95 in September and by more than 13 percent to $105.48 in October, according to Entergy Teaxas.
